ICE-MAIKiNGr MACHINE.

Specification of Letters Patent.

Application filed February 16, 1914.- Serial No.'818,851.

To all whomit may concern:

Be it known that I, JOHN F. SOUTHER, a citizen of the United States,residing at Arlington,- in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Ice-MakingMachines, of which the following is a specification.

This invention relates to machines for making ice, the same beingparticularly adapted for use by private individuals so that they mayduringthe cold season prepare sufficient ice. for their own consumptionfor the whole year, the ice thus'prer pared being stored in a suitablyconstructed ice house of suflicient size to hold a years supply.

The objectof the invention is tOPIOVldG a simple and easily operatedmachine for the purpose specified in which there is provided a primaryreceptacle or receptacles into which the water is poured and after saidWater has been frozen in the primary receptacles, the icethus formed issubjected to the freezing operation for another period of time insecondary receptacles contained in the machine of this invention, saidsecondary receptacles being adapted to receive the ice from the primaryreceptacles. It has been found that .where only one receptacle or set ofreceptacles is provided considerable time "is required to freeze thewater into a solid cakeof ice and, therefore, it is chine.

desirable to first partly freeze the water into cakes of ice and thenempty the partly frozen contents of-the first receptacles into a secondset of receptacles wherein the freez--= ing operation can be continuedwhile the first set of receptacles are filled with water to obtain apartial freezing of other cakes of ice. The cakes of ice will be thusfrozen solid with a great saving of time and consequent increase intheeflicienc'y and speed of the machine.

The invention consists in the'combination and arrangement of parts setforth in the following specification and particularly pointed out in theclaims thereof.

Referring to the drawings: Figure 1 is a plan View of my improved icemaking ma- .Fig. 2 is arear elevation of the same. Fig. 3 is a sideelevation'as viewed from the right of Fig. 2.

Like numerals refer to like parts throughout the several views of thedrawings.

'In the drawings, 5 and 6 are side'frames rigidly joined together. bya'base -7. In the upper. part of the machineis a series of primaryreceptacles 8.rigidly fastened together. The receptacles at the oppositeends of said series are provided with trunnions 9 and 10, respectively,which have'bearings in the frames 5 and 6. The trunnion 9 is extended toreceive a gear 11 which is fast thereto. Said trunnion 9 also hasahandle l2 fastened thereto whereby the' same, together with thereceptacles 8, may be rotated. The gear 11 meshes into a pinion l3-rotatably mounted on a stud 14 fast to-theframe 5. The gear 13 meshesinto a pinion l5, whichis loosely mounted on a trunnion 16 fast to oneof the'end receptacles of a series of receptacles 17. The receptacle 17at the opposite end of said series isalso-provided with a trunnion 18journaled to rotate in bearings in the side frame 6.

The pinion 15 has a pawl 19 pivoted thereto whichengages a ratchet 20fast'to the trunnion 16, whereby the'pinion l3' and gear 11 may berotated while the receptacles 17 are held stationary.

Patented Feb. 2, 1915.

It will be noted that each of' the receptacles 17 is provided withtwo'oppositely disposed chambers 2 1- and '22 and that said receptaclesare locked in position-by means of a suitable hook 23 pivotallymounted'on the side frame 5 of the machine. The receptacles 8 are alsolooked againstn'otation by means of a, suitable hook 24 pivoted to theend receptacle8 and engaging'a pin 25 on the side frame 5.

Beneath the receptacles 17 an inclined platform 26 is provided uponwhich the ice is dumped when the receptacles 17 are rotated. It will benoted that the receptacles 8 are frustu-m-shaped and that theycommunicate one with the other by means of the passages 27.

The general operation of the mechanism hereinbefore specificallydescribed is as follows: Assuming the parts to be in the positionillustrated in the drawings, the primary receptacles 8 are filled withwater. After the water has become frozen into cakes of ice, although notfrozen solid to the center, the operator unlocks the primary receptacles8 and secondary receptacles 17 by unlocking the hooks 23 and 24 and thenrotates the primary receptacles by means of the handle 12. This rotationwill cause the pinions l3 and 15 to be rotated and consequently thetrunnions 16 and 18, together with the secondary the pinion 15, aquarter rotation'of said gear 11 will cause the gear 15 to make a halfrotation. When the gear 11, togetherwith the receptacles 8, has made aquarter rotation, the ice will slide out of the receptacles 8 and intothe uppermost chamber 21 of the receptacle 17. The operator then hooksthe receptacle 17 in position by means of the hook 523 and reverses thedirection of motion of the handle 12 and the receptacles 8 to bring themback to the position illustrated in the figures iof'the drawings readyto be filled again with water for the manufacture ofanother set of cakesofice.

During this backward rotation of the receptacles 8 the pawl 19 will slipover the teeth of the ratchet 20 without rotating the same, thus leavingthe receptacles 17 station-. ary while the receptacles 8 are being movedback to their original position. \Vater is then placed in thereceptacles 8 again and the freezing operation takes place, both withreference to the contents of the receptacles 8 and the contentsofthereceptacles 17. At the next partial rotation of thereceptacles 8,which is performed as hereinbefore described, the contents of saidreceptacles 8 will be dumped into the uppermost chamber in thereceptacles 17, while the ice will be ejected from the lowermostchambers in said receptacles onto the inclined platform 26 and willslide outwardly from the machine in readiness to be taken by theoperator'and placed in an ice house.

Having thus described my invention, What I claim and desire by LettersPatent-to secureis: v

1. An ice making machine having, in combination a rotatablefruStum-shaped pri mary receptacle for ice, a secondary receptacle forice located below said primary receptacle and adapted to receivethecontents of said primary receptacle when the latter is rotated, andmechanism adapted to simultaneously 'rotate said receptacles, wherebythe contents of said secondary receptacle may be ejected therefrom andthe contents of said primary receptacle received thereby.

2. An ice making machine having, in combination, a rotatablefrustum-shaped primary receptacle for ice, a secondary receptacle forice located below said primary receptacle andhaving a plurality ofchambers therein, each of said chambers adapted to receive successivelythe'contents of said primary receptacle when the latter is rotated andmechanism adapted to simultaneously rotate said receptacles, whereby thecontents of said secondary receptacle may be ejected therefrom and thecontents'of said primary receptacle received thereby.

3.
